After 5 years of driking coffee every morning, Now I quite, the reasons? First, Coffee affects my stomach, I dont feel hungry. After taking a glass of coffee, my body is more tress like strong emotion than normal. I always feel hot several hours after drinking strong coffee, I would say, but the good things about coffee is making me more creative. So I dont think every one can drink coffee, I'ts depending upon the organisim of your body. I was addicted to coffee something like I cann't live a day without it. But no it's ok, and I feel more comfortable with other drink like fresh tea.
